Heifer rearing practices may have an influence on performance and longevity in the herd. After feed costs, heifer replacement costs are the largest expense for dairy herds worldwide. Researchers in Sweden evaluated various factors for their influence on longevity of heifers within herds. Raising calves from 3-7 months of age in slatted pens in groups of 7 calves or greater was associated with higher culling risk. Changing housing situations (likely a source of stress) more than four times prior to calving was also associated with decreased longevity. Animals housed in tiestalls, rather than cubicles were also at risk for culling. Adjusting management of heifers can have an impact on longevity in the herd.
